Answer:
Here we have the equation:
y = 4*x^2 - 4*x - 1
And we should have the graph (you can see it below this answer)
Now we want to find the solutions of:
4*x^2 - 4*x - 1 = 0
These solutions will be the two values of x at which the graph of our function intersects the line y = 0, that is the x-axis.
Then we need to find the two values of x at which our graph intersects the x-axis.
In the graph, we can estimate the solutions as:
x = -0.2
x = 1.2
To find the exact solutions we can use the Bhaskara's equation, and we will find that the solutions are given by:
Then the two solutions are:
x = (4 + 5.66)/8 = 11.2075
x = (4 - 5.66)/8 = -0.2075
Answer:
B. cos(ln(2x))/x
Step-by-step explanation:
We know that the inverse of sin is cosine. Note, arcsin means the same thing as inverse sin:
Because sin (a) = sin (b) --> a = arcsin (b)
- Therefore: ln(2x) = arcsin(y)
- Solve ln(2x)=arcsin(y) for x
- (e^arcsin(y))/2
Subsitute y = x
- (e^arcsin(x))/2
- Therefore, we get the answer as cos(ln(2x))/x
I’m confused on the question.?
Answer:
95*6.5%= 6.18
95-6.18=88.82
27.95+88.82= $116.77
